Auto Remove Background Android App Issue

I have an android auto remove background app, I use Huawei MLkit, but I'm facing this issue :
Your app contains content that doesn’t comply with the Device and Network Abuse policy. We found your app is using a non-compliant version of Huawei Mobile Services SDK which contains code to download or install applications from unknown sources outside of Google Play.

I need a developer to create own library without using any api.
